Application filed January 17, 1925. Serial No. 3,063.

The length of the part 13 is suchthat the This invention relates to aspeed handle wrench extension and among the objects of a bowed member 2,having a crank handlethe invention are the provision of an article ofthe character set forth which is simple in'construction and which isquite-effective in action.

In the drawing accompanying and formng part of the presentspecification, there 1s represented in detail a form of embodiment berof respects within the scope of the invention defined by the claimsucceeding suchdescription.

Referring to-said drawing:

Fig. 1 is an elevation of a wrench extension involving the invention,the view. also illustrating an element of the wrench at the right. i V yFig. 2 is a sectional elevation of the upper part of the wrenchextension with the handle in cross section.

Fig. 3 is a cross section on the line 33 of Fig. 1 looking toward theright.

4 is a longitudinal section.

Like characters refer .to like parts throughout the several views. U

As shown, the wrench extension comprises portion 3 near one end and ashank 4 near the other end, upon which is suitably mount ed for freerotation a head 8, which may be locked thereto in any'suitable manner,as by a spring ring .6 located within complementary grooved portions ofthe shank and the lower end 7 of the handle. One of the grooves is shownat 5 (Fig. 2). At the lower end of the crank handle portion 3 is a rightangled extension 9,'to which is secured a socket 10, the end of whichterininates short of aline coincident. with the axis of the shank 4."The outer end of the socket 10 is provided with an angular openingdesigned to receive the angular end 13 of a wrench bar 14, which end 13may be pro- 1 vided with a spring pressed detent 16, to

frictionally hold the bar 14- in the socket.-

seated in said socket.

The socket 10 ispreferably'attached to the 'extension 9 by'means of the pin 11, and theinside of the cavity for receiving the wrench bar extension 13 may.befrecessed, as at 17, forreceiving' the detent 16. It will be observedthat when the parts are assembled the main body 14 of thebar is held insubstantial alignment the speed handle.
